DTC INDEX

APP Sensor Signal Inspection

Note. This procedure checks the APP sensor in its fully closed position. In any other position, the APP sensor stores DTCs which are covered in other troubleshooting procedures. Check for Temporary DTCs or DTCs with the HDS before doing this procedure. If any DTCs are indicated, troubleshoot them first, then do this procedure. Press the accelerator pedal several times to check its operation. If it does not operate properly, check the pedal, the throttle cable, and the APP sensor individually. If you find a problem in one of them, replace the part(s) that caused the problem.

Scheme 52

Scheme 52: APP Sensor Signal Inspection
  1. Connect the HDS to the data link connector (DLC) (A) located behind the driver's side of the front console.
  2. Turn the ignition switch ON (II).
  3. Make sure the HDS communicates with the vehicle and the ECM. If it doesn't, go to the DLC circuit troubleshooting (see «DLC CIRCUIT TROUBLESHOOTING»(ref-351945-S34342936082009122900000) ).
  4. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS. If it is below 2%, the APP sensor is OK. If it is above 2%, adjust the throttle cable (see «THROTTLE CABLE ADJUSTMENT»(ref-221344-S11008582622006022400000) ), then go to step 5.
  5. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS. If it is below 2%, the APP sensor is OK. If it is above 2%, update the ECM if it does not have the latest software, or substitute a known-good ECM (see «UPDATING THE ECM»(ref-221338-S06618208692006022400000) ), then go to step 6.
  6. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the HDS. If it is below 2%, the APP sensor is OK. If it is above 2%, replace the APP sensor (see «APP SENSOR REPLACEMENT»(ref-221340-S24350517622006022400000) ), then go to step 1 .

Scheme 53

Scheme 53: Throttle Actuator Control Module Replacement
  1. Remove the passenger's dashboard lower cover (see «PASSENGER'S DASHBOARD LOWER COVER REMOVAL/INSTALLATION»(ref-221367-S01244536242006022400000) ).
  2. Push the tab (A), and disconnect the throttle actuator control module 16P connector (B).
  3. Remove the nuts (C), and the throttle actuator control module (D).
  4. Install the control module in the reverse order of removal.
